@article{Sundaresan2011LocationEO, title={Location Estimation of a Random Signal Source Based on Correlated Sensor Observations}, author={A. Sundaresan and P. Varshney}, journal={IEEE Transactions on Signal Processing}, year={2011}, volume={59}, pages={787-799} }

The problem of location estimation of a source of random signals using a network of sensors is considered. A novel maximum-likelihood estimation (MLE) based approach using copula functions is proposed. The measurements received at the sensors are often spatially correlated and characterized by a multivariate distribution. Using the theory of copulas, the joint parametric density of sensor observations (joint likelihood) is approximated assuming only the knowledge of the marginal likelihood… CONTINUE READING
